Application April 5, 1940, Serial N0.

In- Belgium December 4, 1934 4 Claims.

My invention relates to a device for intimately mixing a large volume of a gas, such as air, with a liquid such as water, and ordinarily is used for producing a jet of water containing air bubbles disseminated throughout the jet and is an improvement on my Patent 2,210,846 granted Aug. 6, 1940. Such -a jet is whitish in appearance, soft and light to the touch and possesses numerous advantages not found in the ordinary Water jet as discharged from a faucet.

IGenerally speaking, my invention consists therefore of a device comprising a chamber, the inlet end of which is adapted for connection with the discharge end of a tube, such as an ordinary household Water faucet, containing water under the normal main pressure of about 3 atmospheres. The outlet end of the device is adapted to discharge a coherent jet containing air bubbles disseminated throughout the jet. At the upstream end of the chamber is an apertured diaphragm through which the stream of water is adapted to be forced into the chamber with substantial velocity. An 'air port opening into the chamber is provided through which air is induced by the stream of water. At least one foraminous screen is provided in the path of the stream of water after it leaves the apertured diaphragm and before it discharges at the outlet end, for nely breaking up the stream of water which is thoroughly mixed with the air.

Means are provided for thereafter uniting the aerated water to form a coherent j et having small bubbles disseminated throughout the jet. This may be in part, a multiplicity of orifices in the upstream diaphragm; or in the addition of at least a second foramnous screen between the first screen and the outlet end, with openings so close to each other that the issuing aerated water unites to form a coherent jet; or, in the addition f a tubular portion at the outlet end and adapted to contract the stream of aerated water issuing from the screen, to form a coherentjet.

Referring to the drawing Fig. 1 is a vertical section invention.

Figs. 2 and 3 are similar forms.

In Fig. 1, I employ the same type of rubber tap connector 2 as in Fig. 1 of my aforesaid patent, except that I provide a constricted orifice Il, above the upstream apertured diaphragm I8, and the air inlets I9 terminate close to the surface of the downstream screen 20.

In Fig. 2, I employ a screw coupling 2i having sections of modified of one form of my4 a restricted orifice 22 for connecting my device to 55 a faucet and I employ two spaced apertured diaphragms 23, 24 located above the air inlets 25 and I use three spaced screens 26, 21, 28, in the downstream end o1' the device.

In Fig. 3, I employ the same general type of rubber tap connector 30 as in Fig. 1. The metal now of the bubbly jet.
